Configuration Center (Nacos)

Unified registry/config; multi-environment grouping; centralized management of sensitive parameters (hot reload)

Notes - Centralized management for business and gateway configs (e.g., application-*.yml, ruoyi-*-dev.yml), separated by Group/Namespace per environment. - Sentinel rules (Flow/Degrade, etc.) are delivered via Nacos with resource names consistent with code, supporting hot updates and rollback.
